Sunsets. Have they been done to death? Sure they have. Are they a photographic cliche? One of the worst, right up there with cats. Will I resist the urge to grab the nearest camera and tripod every time I see an especially beautiful example of one? Not a chance!
Photography is all about light, very literally. Sunsets are also about light, and also contrasts. Orange/red contrasting with blue/purple. Dark silhouettes against the twilit sky. Day becoming night.
Yes, it’s a cliche. No, I don’t care.
